The Library. A fabulous construct that illuminates The City's sky like a star. For some, it represents an ideal of freedom. For others, It's a glorified prison. During the reception of a very angry widow, something peculiar affected the library, an outside force plucked those prisoners out of The Library and sent them to a world filled with weird colorful teenagers and bad writing. Should I do it? Yeah, I'll repost this, why not? Maybe this will inspire people to make Library of Ruina stuff. ~ Some dude i met in the discord Comrade Author is likely the creator of Bamboo Hatted Kim's edit I used in the cover. Should you so desire, I shall remove it.

If you hear the word reincarnation nowadays, it is usually an untrue fairy tale of being transported into a new world and overcoming the greatest evil to bring about a glorious peace. Yet that unrealistic scenery gets pummeled by the extent of reality. A world too cruel where strength was all that mattered and moral principles were unimportant. The life of the weak is as cheap as dirt. Everyone has died. The same goes for me. Yet again, the raging rides of fate shifted me into a new world once more. So... peculiar. Absurd. Cruel, even. The curse of immortality, stripped of the right to rest. Maybe I just have that lingering desire to live despite it all. Destruction shall befall those who gets in my way. Permissiveness I shall embrace. Nonintervention to those who knows their place. A new reality's beginning... heralded by life and death.
